5 Sheets-Sheet 3 Filed 001;. 22, 1943 and Patented Oct. 17, 1944 UNITEDSTATES PATENT OFFICE VEHICLE JACK James Walter Scane, Windsor, Ontario,Canada Application October 22, 1943, Serial No. 507 326 4 Claims.

The present invention relates to new and useful improvements in vehiclejacks and has for its primary object to provide a jack adapted forengaging the brake drum of a vehicle wheel and embodying means foraccurately centering the jack under the drum and which rig'idlyholds thevehicle in its elevated position against accidental displacement fromthe jack.

A further object is to provide a jack of this character of simple andpractical construction, which is. strong and durable, relativelyinexpensive to manufacture, and otherwise well adapted for the purposesfor which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a top plan View.

Figure 2 is a side elevational view.

Figure 3 is a longitudinal sectional through the screw guide.

Figure 4 is-a sectional view taken on a line 4-4 of Figure 2. V

Figure 5 is a transverse sectional view modified form of base.

Figure 6 is a top plan view of a modified jack construction.

Figure 7 is a side elevational view thereof, and

Figure 8 is a side elevational View of the detachable lift plate.

Referring now to the drawings in detail, the numeral 5 designates achannel base having a pair of ears 66 rising from the side edges of thebase at one end thereof and between which is mounted a transverse pin 1pivotally supporting a lug 8 projecting downwardly from a collar 9 viewofa

having a sleeve l extending from one edge thereof. Formed on theopposite edge of the collar is a frame-like bracket ll having an openingi2 in its outer side in alignment with the bore of the collar 9 andsleeve II]. A screw I3 is freely positioned in said opening and bore andis threadedly engaged with the internal threads of a gear M positionedwithin the confines of the bracket 1 l. A washer I is placed between thegear and the adjacent edge of the collar 9.

Also positioned within the confines of the bracket and engaging the gearI4 is a gear [6 having a shank l1 journaled in one side of the bracket,the shank having a socket 18 at its outer end for receiving amanipulating handle adapted to rotate the gears and to thus feed thescrew longitudinally of the sleeve.

drum.

A yoke I9 is formed onone end of the screw having a transverse pin 20*to which the downwardly ofiset rear end of a lever 2| is pivotallyattached. The intermediate portion of the lever is pivoted on a, pin 22extending transversely of a pair of ears 23-23 rising from the upperedges of the base 5. v

The front end of the lever 2| is offset toward one side of the base andis provided with a transverse pin 24 on which an inverted U -shapedmember 25 is pivotally mounted. 7

To one side of the-member 25 is welded or otherwise suitably secured alift plate 26 which is curved longitudinally and provided with anupstanding flange 21 at its outer edge, the plate being adapted toengage under a brake drum with the flange 21 engaged behind the usualflange of the dust shield of the drum to prevent slipping of the liftplate therefrom.

A coil spring 28 connects the member 25 with the lever 2| to yieldablymaintain the lift plate in a horizontal position and to permit selfadjusting of the plate when engaging the brake pair of ears 2929 projectfirom one side of the base 5-having a vertical pin 30 and to which ispivotally attached a flanged arm 3| adapted to project laterally fromthe base at right angles thereto, or the arm may be swung inwardlyagainst the side of the base 5.

In Figure 5, I have illustrated a modified base construction 32 having asingle upstanding web or flange 33 and to which the several parts foroperating the jack may be pivotally mounted.

In the operation of the jack, the base 5 is placed under the caralongside of the deflated tire and with the arm 3| disposed transverselyof the tire and in engagement therewith. This position will center theplate 26 under the brake drum of the wheel and upon the operation of thegear It in a desired direction by a suitable handle, the gear l4 willmove the screw l3 forwardly thereby forcing the rear end of the lever 2|downwardly and raising the front end of the lever and lift plate toelevate the wheel.

Figures 6-8 inclusive represent a modified jack construction andincludes a base 34 of channel shape in cross section having a pair ofposts 35 rising therefrom and between the upper end of which is pivotedthe lift arm or lever 36 by means of the pin 31. The rear end of the armis actuated as heretofore explained by the screw 38 except that a pairof operating gears 3939. and sockets 40-40 are provided at oppositesides of the jack for operating the screw from either side.

The front end of the arm 36 is provided with a transverse pin 4| towhich the intermediate portion of a leg 42 is pivoted, the upper end ofthe leg having a channeled lift plate 43 fixed thereon and adapted toreceive the axle of the vehicle or other part thereof. A pair of bracerods 4444 are pivoted at one end at opposite sides of the lower end ofthe leg 42 while the other ends of the rods are pivoted to the posts 35,the brace rods maintaining the lift plate in a horizontal positionduring raising and'lowering of the arm 36.

An adapter lift plate 45 is also provided and has its leg portion 46insertable through an opening 41 of the lift plate 43 into a socket 48carried by the leg 42 of the lift plate 43, any desired number of theadapters being provided and of various heights to properly engage thepart of the vehicle to be lifted under varying conditions.

A pair of the pivoted lateral arms 49-49 are also provided for engagingthe deflated tire when the jack is used at either side thereof. The

arms 3| and 49 facilitate location of the jack with respect to the partof the vehicle to be engaged by the lift plate, so that it isunnecessary to crawl under the car to check the location of the jack. Bypivoting these arms, they may be compactly folded alongside the basewhen not in use. Also, the sleeve l and one of the arms 49 or arm 3| maybe readily grasped to facilitate slipping of the jack into place bymerely stooping slightly. In addition, the jack has great stability dueto the long base, and it is quite practical to jack up a car on aconsiderable grade without setting the brakes or chocking the wheels,because this elongated base is adapted to lie directly on the groundsubstantially from end to end.

It is believed that the details of construction and manner of use of thedevice will be readily understood from the foregoing without further adetailed explanation.

what is vehicle, a lever pivoted intermediate its ends to the base,screw means carried bythe base and connected to one end of the lever toraise or lower the opposite end thereof, said last-named end of thelever being laterally offset beyond one side of the base, a memberpivoted on the outer offset end of said lever, a lift plate pivotallycarried by the member and having an upstanding flange on its outer edgeadapted to engage behind the flange of a brake drum, and spring meansconnected to the member to yieldably maintain the lift plate in apredetermined position.

2. A vehicle jack comprising a channeled base adapted to lie on theground along one side of a vehicle wheel, a collar pivoted on the base,a screw freely mounted in the collar, a bracket on the collar, aninternally threaded gear on the screw, a manually operable gear carriedby the bracket and engaged with the first-named gear, a lever pivotedintermediate its ends on the base and having one end pivoted to thescrew for raising and lowering the other end of the lever, and a liftplate carried by said lastnamed end of the lever.

3. A vehicle jack comprising a base adapted to lie on the groundalongside a wheel of the vehicle, a lever pivoted intermediate its endsto the base, screw means carried by the base and connected to one end ofthe lever to raise or lower the opposite end thereof, a lift platecarried by the last-named end of the lever, and a rotatable operatingmember for said screw means located at one side of the base and mountedon an axis extending transversely of one end of the base.

4. A vehicle jack comprising an elongated base adapted to lie on theground alongside a wheel of the vehicle, lifting mechanism mounted onthe base including a lift plate, and arms carried by and extendinglaterally from* opposite sides of the base and selectively engageablewith the tire of the wheel at either side of the vehicle to facilitatelocation of the jack with respect to the part of the vehicle to beengaged by the lift plate.
